How Installing Energy-Efficient Windows in Castle Pines Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Castle Pines, that’s about 460 pounds per year on average.
  • Save on power bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $443 annually on your energy bills in Castle Pines.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Castle Pines

Let’s go over the cost of replacing your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Though the national average cost to replace one window is around $600, it can range from $200 to $1,200. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will make your project cost more.

It’s also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that switching out the windows on your Castle Pines home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re still trying to decide which kind of installation you need, you can ask your installer and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Castle Pines

EcoWatch reviews differ from other reviews since we assess these companies through a sustainability lens. We’ve evaluated the best window replacement companies in Castle Pines primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Castle Pines’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Castle Pines window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Castle Pines, CO Window Replacement FAQs

How much does a window install cost?

The average cost to install one window can range from $450 to $650. There are several factors that affect how much it costs, which include your property’s location, styles and sizes of windows, the number of windows, local labor costs, the materials used in designing the windows and how energy-efficient the windows are.

What kind of window is the most energy-efficient?

A window’s energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

What services do window installation companies do?

Window installation companies will do the entire process — from replacing your old windows with brand-new ones to cleaning up after the installation. In addition, a lot of companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.

Should I replace all my windows at once?

If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
